Q.Ladybugs
If you sell ladybugs, can you email me to let me know when I can buy some? I will have a home made for them, which I am sure they will enjoy. I know the simple way of making one. I hope you can help. If not, I know other people that sell them.
Thanks for your time.

PS: I have a terrible green and white fly in my greenhouse, maybe spider mite too, so any tips would be good until I get the ladybugs.
